Improvement in derricks



NEWTON MATLICK, OF WILLIAMSTOWN, MISSOURI. Letters .Patent No. 89,416, (lated April 27, 1869.

IMPROVEMENT IN DERRICKS.

To all whom it may concern:

Be it known that I, NEWTON MATLICK, of Williamstown, in the county of Lewis, and State of Missouri, Vhave invented a new and improved Derrick; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which the ligure is aside view of-my'irnproved derrick, part being broken away to show the' construction.

. My invention has forits object to furnish an improved derrick, which shall be simple in construction, easily moved ii'om place to place, and conveniently operated,

raising the hay or other weight, and at the same time and by the same operation, swinging it into the position in which it is to be placed; and

It consists in the construction, combination, andarrangement of the various parts, as hereinafter more fully described.

`A is the base, or foundation-frame of the machine,

the side-bars c of which, are, made deep, and have their forward ends bevelled off, so as to serve as runners for transporting the machine. To the middle part of the frame A, is secured the lower end. of the vertical post B, the upper end of which passes through which is still further secured in place, and supported against side strain by the braces D, the upper ends of which are attached to the corners of the block C, and the lower ends of which are attached to the corners of the foundation, or base-frame A.

To the upper end of the post B is pivoted the block E, by means of a pin formed upon the lower end of said block, which enters a socket formed forits reception in the upper end of the said post B.

Upon the upper end of the pivoted block E, are formed ears, between which is pivoted the crane-arm, or lever F, so that the said lever may have both a ver- `tical and lateral movement.`

G is an inclined brace, the upper end of which is pivoted, or hinged to the forward part of the long arm of the lever F, andthe lower end of which is pivoted to the lowcr part of one of the braces D, or to the frame A, so that as the lever F is moved later'- ally by the action of the hoisting-rope H, the forward the block, or platform 0, and l end of the said lever F may at the same time be raised by the combined action of the hoisting-rope H, and hinged or pivoted brace G.

H is the hoisting-rope,to one end of which the weight to be raised is attached.

lhe rope H passes from the weight to be raised, over the pulley I, pivoted to theforward end of the lever F, along the upper side of said lever, and over the pulley J pivoted to the end of' its short arm.

From the pulley J the rope H passes around the pulley K, pivoted to the base-frame A, and to its other end the hoisting-power is attached.

By this construction and arrangement of the parts of the derrick, as the power is applied to the rope H, the first effect is to raise the weight from the ground.

When the weight being raised strikes against the end of the lever F, if the application of power is continued, the next effect is to move the forward end of the lever F laterally, and at the same time raise it, and with it the weight, thus bringinglthe weight into the desired position.

In cases in which it is not desired to raise tne weight so high, the lateral movement of the lever F may be made to begin at any point, by forming a loop upon the rope H, at the proper point between the weight to be raised, and the end of the lever F, and passing through this loop a pin, and the lateral movement will begin as soon as thesaid pin strikes against the said lever F.

rIhis enables the weight to be raised to and deposited at any desired height.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- An improved derrick, formed by the combination of the pivot-block E, pivotcd lever F, inclined pivoted, or hinged brace G, pulleys I, J, and K, and rope H, with each other, andwith thel supporting frame-work A c B C D, said parts being'arranged and operating Vsubstantially as herein shown and described, and for the purpose set forth.
